## What is CVE-2007-0842?

CVE-2007-0842 is a medium-severity denial of service vulnerability in n/a, published on 13 Feb 2007. 

### Official description

The 64-bit versions of Microsoft Visual C++ 8.0 standard library (MSVCR80.DLL) time functions, including (1) localtime, (2) localtime_s, (3) gmtime, (4) gmtime_s, (5) ctime, (6) ctime_s, (7) wctime, (8) wctime_s, and (9) fstat, trigger an assertion error instead of a NULL pointer or EINVAL when processing a time argument later than Jan 1, 3000, which might allow context-dependent attackers to cause a denial of service (application exit) via large time values. NOTE: it could be argued that this is a design limitation of the functions, and the vulnerability lies with any application that does not validate arguments to these functions.  However, this behavior is inconsistent with documentation, which does not list assertions as a possible result of an error condition.

Weakness: CWE-399

## Fix prompt for AI coding agents

```text
Check this codebase for CVE-2007-0842 and fix it if it is affected.

What it is: CVE-2007-0842 is a medium-severity denial of service vulnerability in n/a, published on 13 Feb 2007. 
Exploitation: There is no known exploitation of CVE-2007-0842 in the wild and no public exploit code.

Affected product: n/a. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
